Well what you say makes some sense, because the blue above the clouds (upper) actually divides the frame into fourths.. and possibly this would cause an eye distraction,, perhaps a crop into the cloud itself would be more pleasing..
yes, it looks nice, but something bothers me.. not sure what yet. it looks a bit out of balance for me, maybe because of the snow which has not much structure, and then the upper 3/4 have lots of detail and colour.
maybe just too much sky and not enough snow for my eyes.
no not too simple - just a nice clean picture and you have done the snow very well. I think I would crop a touch off the left as I feel the barn is too central.
Well done
